First, these screws are short. Second, these threads are small and tight. A total waste of money. Do not recommend.
The chrome caps attach very securely to their keepers and, imo, look very nice next to a silver frame. Got these to install a relocated obdii port due to the black anodizing of bolts & the snap on bolt head covers to match my interior color.
I like them because they don't rust! Solid and seems strong. It actually makes it a really clean, custom look. I also like the fact that they are reasonably inexpensive and look great!
Love the included accessory bit head and tool. Haven't had any other encounters with people since then, but at least i'm prepared now. Plenty of extra bits to fit various situations.
These screws are 1/4 diameter. Was only able to install 3 out of the 4 screws. The screws are too big for plate mounts on u.
